MOLDING-FLASK.

Specification of Letters Patent.

Patented Jan. 24, 1911.

To all whom it may concern:

Be it known that we, ABRAM O. Mo'r'r, Jr., and J AMES VVHITEHEAD, citizens of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Molding-Flasks, of which the following is a specification.

One object of our invention is to improve the construction of flasks used in molding, whereby the flask can be used either with or without the match pattern.

A further object of the invention is to so hinge the cope and match patterns to the drag that the match can be more readily handled than heretofore.

In the accompanying drawings :Figure 1, is a perspective view of our improved flask open and with the match pattern in position; Fig. 2, is a perspective view of the flask closed; Fig. 3, is a side View; Fig. 4;, is an end view; Fig. 5, is a sectional view on the line 55, Fig. l; Fig. 6, is an enlarged view showing the fastening for securing the cope and drag, the match pattern being in position; Fig. 7, is a similar view to Fig. 6, without the match pattern; and Figs. 8, 9 and 10, are perspective views illustrating details of the invention.

A is the drag section of the flask, B is the cope, and O is the match pattern located between the cope and drag, as illustrated in Fig. 5. At the rear end of the flask is a pair of hinges E; the socket portion 6 of each hinge is secured to the drag A and a pin 6' is secured to the cope. The socket is open so that the cope can be detached from the drag when necessary. At the opposite end of the flask is a lock consisting of a pivoted segmental bolt D having an opening cl; the free end d of the bolt is tapered and has a projecting lug 0Z The opening at in the bolt is beveled, as shown, and fits loosely on an inclined projection f of a plate F secured to the cope B, so that 'it can be readily removed when desired, but when in engagement with either of the keepers g, g on a plate G it will hold the parts firmly together. The plate G is secured to the drag A and the two keepers are arranged one below the other, and the under face of each keeper is beveled to fit the beveled portion of the bolt D. When the match pattern O is mounted between the cope and drag,-

then the bolt will engage the keeper g, and

when the match pattern is removed the bolt will engage the keeper 9 and this bolt can be readily slipped off of the projection f when desired. On the plate G is a projection g which is used as the fulcrum of a lever when forcing the bolt into position. The lever will engage the projection (Z on the bolt and the projection 9 By this means the bolt can be secured without the use of a hammer and the sand in the flask will not be disturbed. On the cope B, in the present instance, are plates I having pins 2' which enter openings 72, in plates H secured to the drag A, so that when the flask is closed the cope and drag are held in alinement.

The match pattern O has two hinge pintles 0, c at one end, which rest in sockets h in the plates II. At the opposite end of the match pattern are pins 0 which enter openings in the drag, so that when the match pattern is in place it is held rigidly by the pins 0 and the pintles c. c is a lip of the match pattern which can be engaged by the hand to turn the match pattern on its hinge pintles when it is wished to lift the pattern from the drag.

The bottom board N is mounted under the drag A and on each side of the drag is a plate F having a pin f, and one of the bolts D is mounted on each pin and engages a plate G secured to the bottom board, as shown in Figs. 1 and 3.

By hinging the match pattern on the oposite side of the hinge of the cope we are enabled to first turn the cope back, then turn the match pattern in the opposite direction so that it will be in easy position for the molder to lift it from the drag and transfer it to the point desired. This is particularly advantageous in makingcomparatively large castings where the metal match patterns are heavy.

In making the mold the match pattern O is placed in position between the rope B and drag A and the bolts 1) are applied so that the parts will be held together, the bolt engaging the keeper 9 as in Figs. 4 and 6. The flask is inverted with the drag on top, the sand is then properly rammed and the bottom board applied and secured to the drag by bolts D, which engage projections on the plate G, then the flask is turned over and the cope rammed, after which the cope is detached from the drag and turned back on its pivot and the match pattern is turned in the opposite direction on its pivot and removed, the cope is then closed and secured by the belt which engages the keeper g of the plate G, and the flask is then made read for pouring.

e claim 1. The combination in a flask, of a cope, a drag, a match pattern arranged to be mounted between the two sections of the flask, a segmental bolt attached to one part, and two keepers attached to the other part arr: nged to be engaged by the bolt.

2. The combination in a flask, of a cope section, a drag section, the two sections being hinged together at one end, a segmental bolt attached to the cope, a double keeper on the drag, a match pattern arranged to be mounted between the two sections of the flask, pins on the match pattern arranged to enter openings in the drag, pins on the cope arranged to enter openings in the drag, a bottom board, and means for attaching the bottom board to the drag.

The combination in a flask, of a cope section, a drag section, a match pattern pivoted at one edge to the drag and having pins at the other edge entering openings in the drag, and having a lip by which it can be raised and turned on its pivots.

at. The combination in a flask, pf a drag, a cope section pivotallv connected thereto, a match pattern pivotallv connected to the drag, a pin on the match pattern entering an opening in the drag, brackets on the drag, pins on the cope entering the openings in said brackets. bolts attached to the drag, a

bottom board, and plates on the bottom l l t l l t t l l t t l l l l board arranged to be engaged by the bolts inclined projection, the bolt having a beveled opening through which the projection freely passes, a plate on the other section having a beveled keeper engaged by the bolt.

6. The combination in a flask, of a segmental bolt for securing the parts of the flask together, a plate on one part having an inclined projection, the bolt having a beveled opening through which the projection freely passes, a plate on the other section having two keepers beveled on their undersides and located one below the other.

T. The comliiination in a molding flask, of a bolt for securing the parts together and having an aperture; a plate on one part of the flask having an inclined projection passing through and of smaller diameter than the aperture in the bolt; a plate on the other section of the flask having two keepers, each of said keepers adapted for engagel'l'lQlltjWltll the bolt; and means including a projection on the bolt and a projection on one of the plates for tightening and loosening the bolt in engagement with either keeper.

In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses.
